The JAC Refine K5W Heavy Duty Standard Load Version 390HP 8X4 5.6m Dump Truck is engineered to solve a unique challenge: moving extreme weights in tight industrial spaces. Whether you’re transporting 20-ton precast concrete beams between factory workshops, hauling steel coils through narrow port storage yards, or delivering heavy foundation materials to a high-rise construction site wedged between urban buildings, it pairs brute strength with surprising agility. Powered by a Weichai WP12.390E62 diesel engine, it delivers 390 horsepower and 1600 N·m of torque at 1200-1800 rpm—enough to climb 18° loading ramps (common in manufacturing plants) with a full load, while the 8X4 drive setup distributes weight evenly to avoid damaging factory floors or urban pavements. Paired with a Fast 12JSD200TA 12-speed manual transmission, it shifts smoothly between slow, precise movements (critical for navigating between factory machinery) and steady speeds on short-haul industrial routes. Its 5.4-meter turning radius is a standout—letting it pivot in spaces that would strand longer 8X4 dump trucks.
What makes this standard load model unique is its 5.6m×2.45m×1.5m dump body, engineered for heavy, dense loads rather than bulk volume. Constructed from Q960 ultra-high-strength steel (with 500HB wear resistance), the body withstands concentrated pressure from steel coils or concrete blocks without warping, while its low-profile design (1.2m loading height) simplifies loading with factory overhead cranes. The hydraulic lifting system uses a dual-cylinder setup for controlled, wobble-free raising—critical when unloading 20-ton beams near delicate equipment—and lifts a full load in 22 seconds, fast enough to keep pace with factory production schedules. Underneath, a reinforced double-layer frame (300×85×(14+12)mm) and 13/13/16-leaf spring suspension with shock absorbers minimize vibration, protecting both the cargo (like precision-engineered components) and the truck’s chassis during daily industrial use. It also features a reinforced rear bumper and proximity sensors to prevent collisions in crowded yards.
For industrial fleet managers focused on operational precision and cost control, the K5W Standard Load delivers clear value. Its 380L fuel tank handles a full day of 8-10 short industrial runs (150+ km) without refueling, and the Weichai engine’s optimized fuel injection keeps average consumption at 30-32L per 100km—impressive for its power class, especially during frequent stop-start yard maneuvers. Maintenance is tailored for industrial reliability: the engine uses 20,000km long-life oil, and key components like the clutch and hydraulic pump are reinforced for heavy, repetitive use (reducing downtime by 25% vs. standard 8X4 models). Inside the cab, practical features support industrial shifts: an air-suspended seat with lumbar support (eases fatigue from constant low-speed maneuvering), a 10-inch touchscreen with 360° camera (vital for navigating tight yards), and oil-resistant upholstery (easy to clean after factory visits). It’s the powerful, precise workhorse that brings heavy-lift capability to confined industrial spaces—without sacrificing control or efficiency.
